Abstract
The invention discloses a test fixture of a PCB appearance test desk type microscope, comprising a support plate capable of being placed on the loading disc of a desk type microscope; the upper surface of the support plate is a plane and is provided with a light trough which is formed by sinking the upper surface of the support plate downwards; an LED light source is fixed in the light trough, and is located at the central position on the upper surface of the support plate; the LED light source is not higher than the upper surface of the support plate, and is in connection with a power source. In test, the support plate is placed on the loading disc of the microscope, the switch of the LED light source is turned on, and a PCB is placed on the support plate for testing a defective appearance, which is equivalent to providing a bottom light for the microscope and can help the desk type microscope display abnormality in a hole, thereby allowing the desk type microscope to perform more comprehensive test, and avoid loss.
Description
Technical field
The invention belongs to field of printed circuit board fabrication, be specifically related to outside a kind of PCBSee the desk-top microscopical detecting tool of inspection.
Background technology
PCB producer all will carry out quality pipe in PCB manufacture process and after completingControl, wherein having a project is inspection PCB bad order. In inspection PCB outward appearanceIn bad link, be all generally to adopt desk-top high definition microscope to test. This is desk-topHigh definition microscope generally has a support, is positioned at the bottom of support and is positioned over platformThe load plate of face and be fixed on support and be positioned at the high definition microscope of load plate top, andAnd this high definition microscope is connected with computer, high definition microscope can be along moving down on supportMoving, and can be by showing in the image input computer of observing, so that reviewerObserve bad order. But there is a defect in this high definition microscope: PCB holeInterior anomaly item cannot show confirmation.
Summary of the invention
In order to address the above problem, the invention provides a kind of PCB appearance test platformThe microscopical detecting tool of formula, this PCB appearance test is controlled with desk-top microscopical inspectionProdigiosin enough helps abnormal in desk-top high definition microscopy hole, thereby makes desk-top high definitionComprehensive inspection can be more shown in by microscope, avoids leakage.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of PCB desk-top microscopical detecting tool for appearance test, comprises one yearPlate, described support plate can be positioned on desk-top microscopical load plate, described support plate upperSurface is plane, and the upper surface of described support plate is provided with light trough, and described light trough is by support plateUpper surface forms to lower recess, in described light trough, is fixed with LED light source, described LEDLight source is positioned at the center of the upper surface of support plate, described LED light source not aboveThe upper surface of described support plate, described LED light source connects power supply.
The present invention for the further technical scheme that solves its technical problem and adopt is:
Say further, described light trough is strip groove, and described light trough is from described support plateThe center of upper surface extend to edge, described light trough be opened on support plate upper surface andSide, is provided with square light source fixed head, the width of described light source fixed head with described inThe width of light trough matches and length is less than the length of described light trough, described LED lightSource is fixed on described light source fixed head, and described light source fixed head is inserted by the side of support plateEnter to be embedded in described light trough, described LED light source connects power supply by power line,Described power line is arranged along the bottom surface of described light trough, and described power line is provided with switch.
Say further, described LED light source is white led lamps.
Say further, described support plate is the rectangular slab that upper and lower surface is all plane.
The invention has the beneficial effects as follows: in PCB appearance test of the present invention with desk-topMicroscopical detecting tool is mainly by support plate and is embedded in the LED light source in support plateForm, when inspection, support plate is positioned on desk-top microscopical load plate, and opensThe switch of LED light source, is placed on PCB on support plate, to carry out bad order inspectionTest, be equivalent to make desk-top microscope tool lamp with the end, can help desk-top high definition aobviousMicro mirror shows abnormal in hole, thereby desk-top high definition microscope can be more shown in comprehensivelyInspection, avoids leakage.
